Abstract (en)
[origin: EP0676856A2] An on-board regulated voltage up-convertor for converting a first DC voltage at a first node from an electronic system to a second DC voltage for an integrated device at a second node. The convertor comprises reference generator means for generating a predetermined reference voltage at start-up, voltage regulator means coupled to said first node for regulating said first voltage at a predetermined voltage at a third node, voltage multiplier means coupled to said third node and to said second node for multiplying said predetermined voltage to generate an output voltage substantially equal to said second voltage, feedback means coupled to said second node for feeding said output voltage back to said voltage regulator means to adjust the level of said predetermined voltage at said third node according to how said output voltage is relative to said second voltage. <IMAGE>
